Kadifekale (literally "the velvet castle" in Turkish) is the name of the hill located within the urban zone of İzmir, Turkey, as well as being the name of the ancient castle on top of the same hill.  

Both the hill and the castle were named Pagos (Greek: Πάγος, Pagus under the Roman Empire) in pre-Turkish times and by the local Greeks in modern times.  

The summit where the castle is found is located at a distance of about 2 km from the shoreline and commands a general view of a large part of the city of İzmir, as well as of the Gulf of İzmir. 

Administratively, the hill area covers six quarters constituted by slums in their large part, one named Kadifekale like the hill, and others Alireis, Altay, İmariye, Kosova and Yenimahalle. 

In 2007, the metropolitan municipality of İzmir started renovation and restoration works in Kadifekale.
